Apple Mail.app works just fine. You say you "hate" it without listing the reasons why... which is usually a good indicator that you've never used it.

Why?

Look at this:
Mail vs Sparrow

Too much crap in Mail.app, shows my archived mails etc, and now look at Sparrow.
Yes, I can hide, but still it shows those archived emails etc... It plays with iCloud which I don't need either
Do I need to say anything more about that?

BTW just started downloading Thunderbird. Will post my feedback.

Thunderbird, really not for me. But still better than standart Mail.app
